Levonorgestrel acts on the hormonal pathway that regulates ovulation and implantation, providing contraceptive protection.

- Emergency contraception: prevents pregnancy after unprotected intercourse when taken within a defined time window. - Regular contraception: maintains contraceptive efficacy as part of a combined or progestin‑only regimen for ongoing birth control. - Menstrual cycle regulation: can be used to adjust timing of menstrual bleeding in certain clinical protocols.

Levonorgestrel may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Nausea: mild stomach upset. - Headache: transient cranial pain. - Breast tenderness: discomfort in breast tissue.

Serious or Rare Side Effects: - Thromboembolic events: blood clot formation. - Severe allergic reaction: rash, swelling, or anaphylaxis. - Liver dysfunction: abnormal liver enzymes or jaundice.

When prescribing Levonorgestrel, several precautions should be observed to ensure safe and effective use.

- Pregnancy testing: confirm the patient is not already pregnant before administration. - Timing of intake: take the medication as soon as possible, preferably within 72 hours after unprotected intercourse. - Drug interactions: avoid concomitant use with enzyme‑inducing agents that may lower effectiveness. - Medical conditions: use with caution in patients with liver disease or a history of thromboembolic disorders. - Age considerations: not recommended for women under 18 without medical supervision. - Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel can interact with other medicines, affecting its contraceptive efficacy or safety.

Major Interactions (Avoid): - Rifampicin: strong enzyme inducer that markedly reduces levonorgestrel plasma levels. - Antiepileptic drugs (e.g., carbamazepine, phenytoin): decrease hormonal effectiveness. - St. John’s wort: herbal inducer that may compromise contraceptive protection.

Moderate Interactions (Monitor Closely): - Ketoconazole or other azole antifungals: may increase levonorgestrel concentrations. - Certain antibiotics (e.g., tetracycline, metronidazole): can slightly reduce efficacy. - Estrogen‑containing hormonal therapies: may alter overall hormonal balance.
